Question

除了Locale.getISOCountries（）之外，因为我已经在这方面出现了一些奇怪的错误。还有什么是获得两个字母的国家代码和完整国家名称的最佳方法？

Answer 1

对于一个单独的项目，我从ISO站点。

注意以下事项：

The names are in all caps. You will probably want to tweak it so it s not.
The names are not all in simple ASCII.
The names are not entirely political neutral (it is probably impossible for any purported list of countries to be). E.g., "Taiwan, Province of China" is a name. A good starting point to learn about the issues is this blog post.

Answer 2

请参阅代码片段：

String[] countryCodes = Locale.getISOCountries();

for (String countryCode : countryCodes) {

    Locale obj = new Locale("", countryCode);

    System.out.println("Country Code = " + obj.getCountry() 
        + ", Country Name = " + obj.getDisplayCountry());

}

请参阅Java中的国家列表以获取更多示例。

Answer 3

Create a Map out of this page http://www.theodora.com/country_digraphs.html
Save it to a file (I suggest XMLEncoder/XMLDecoder class)
Create a wrapping class that loads this Map from the file (I d use a lazily initialized singleton) and allows access to the get(...) methods.
Repeat (or use a bi-directional map) these steps for each column of the table on the afore mentioned webpage.
Fancy-Time: Throw in some code to wrap the entries in a Reference object (SoftReference?) so that the Map won t throw MemoryErrors

Answer 4

你可以像下面这样使用from json

Json正在分析。。

String jsonString =JSON_DATA;
ObjectMapper mapper = new ObjectMapper();    
try {
        JsonNode rootNode = mapper.readTree(jsonString);              

        for (JsonNode node : rootNode) {
            String countrycode = node.path("code").asText();
            String dialnumber = node.path("dial_code").asText();
            String countryname = node.path("name").asText();

        }


} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Json字符串在这里

public static String JSON_DATA="

 [
   {
    "name": "Afghanistan",
    "dial_code": "+93",
    "code": "AF"
   }, 

  {
   "name": "Aland Islands",
  "dial_code": "+358",
  "code": "AX"
  },


{
  "name": "Albania",
 "dial_code": "+355",
 "code": "AL"
 },

{
 "name": "Algeria",
 "dial_code": "+213",
 "code": "DZ"
 },

{
   "name": "AmericanSamoa",
   "dial_code": "+1684",
   "code": "AS"
  }]";
